The "Mind Games" pack contain three new spells that deals with controlling your empires happines and cities: Propaganda, Information Warfare, and Auto-Suggestion. The "Propaganda" spell can be acquired at the start of the game when you create your Great Mage. The other two can be researched or found in a monster lair.

The "Heritage of the Dremers" pack contains three new spells related to, as the name suggests, the horrid Dremers: Summon of Evil, Curse of Evil, and Falling Sky.

The ""Summon of Evil"" spell can be acquired at the start of the game when you create your Great Mage. The other two can be researched or found in a monster lair.

Recommended when on sale

Of the Warlock 2 DLCs, I would only recommend picking up Wrath of the Nagas and the Spectacular Spell pack, preferably when on a 75% off sale. Variety is always a good thing in these long games (unless it is seververly imbalancing).
